Detailed Description

Class for wrapping around the OSG Camera class.

It adds some utility functions for simply setting some camera defaults.

Member Enumeration Documentation

◆ ProjectionMode

enum WGECamera::ProjectionMode

List of possible camera modes.

The TWO_D modes use a standard two dimensional orthogonal projection. TWO_D_UNOT is somewhat special. It creates a view-cube with an edge-length of 1, centered at 0 for X and Y. For Z, it is from 0 to 1. This relates to the standard glOrtho command.

Constructor & Destructor Documentation

◆ WGECamera() [1/2]

WGECamera::WGECamera	(	int	width,
		int	height,
		ProjectionMode	projectionMode
	)

Constructor which sets defaults.

Parameters

width	width of the viewport.
height	height of the viewport.
projectionMode	projection mode of the viewer.

Definition at line 31 of file WGECamera.cpp.

Here is the call graph for this function:

◆ WGECamera() [2/2]

WGECamera::WGECamera ( )

Constructor which sets defaults.

Definition at line 54 of file WGECamera.cpp.

◆ ~WGECamera()

WGECamera::~WGECamera ( )

protectedvirtual

Destructor.

This desctructor is protected to avoid accidentally deleting a instance of WGECamera. This follows the philosophy of OSG to avoid problems in multithreaded environments, since these camera pointers are used deep in the OSG where an deletion could cause a segfault.
